12x-3\left(1-\frac{3x}{2}\right)-4\left(2-\frac{x}{4}\right)=24
Multiply both sides of the equation by 12, the least common multiple of 4,3.
12x-3-3\left(-\frac{3x}{2}\right)-4\left(2-\frac{x}{4}\right)=24
Use the distributive property to multiply -3 by 1-\frac{3x}{2}.
12x-3+3\times \frac{3x}{2}-4\left(2-\frac{x}{4}\right)=24
Multiply -3 and -1 to get 3.
12x-3+\frac{3\times 3x}{2}-4\left(2-\frac{x}{4}\right)=24
Express 3\times \frac{3x}{2} as a single fraction.
12x-3+\frac{9x}{2}-4\left(2-\frac{x}{4}\right)=24
Multiply 3 and 3 to get 9.
12x-3+\frac{9x}{2}-8-4\left(-\frac{x}{4}\right)=24
Use the distributive property to multiply -4 by 2-\frac{x}{4}.
12x-3+\frac{9x}{2}-8+4\times \frac{x}{4}=24
Multiply -4 and -1 to get 4.
12x-3+\frac{9x}{2}-8+\frac{4x}{4}=24
Express 4\times \frac{x}{4} as a single fraction.
12x-3+\frac{9x}{2}-8+x=24
Cancel out 4 and 4.
12x-11+\frac{9x}{2}+x=24
Subtract 8 from -3 to get -11.
13x-11+\frac{9x}{2}=24
Combine 12x and x to get 13x.
13x+\frac{9x}{2}=24+11
Add 11 to both sides.
13x+\frac{9x}{2}=35
Add 24 and 11 to get 35.
26x+9x=70
Multiply both sides of the equation by 2.
35x=70
Combine 26x and 9x to get 35x.
x=\frac{70}{35}
Divide both sides by 35.
x=2
Divide 70 by 35 to get 2.
